Figure 1. Distribution map and photographs of Bibarba species. A, type locality of B. bibarba (circle) and B. parvoculus (triangle). The inserted map shows the worldwide distribution of the Northern Clade and the Southern Clade of the family Cobitidae with the enlarged area framed. B, Bibarba species, upper: surface-dwelling B. bibarba (HBU20170801, male); lower: cave-dwelling B. parvoculus (LJH 2016120051, male). C, left pectoral fin of B. bibarba (HBU20170801, male) in dorsal view. D, left pectoral fin of B. parvoculus (LJH 2016120051, male) in dorsal view. Arrowheads indicate the lamina circularis on second and third pectoral rays. Scale bar: 10 mm in B, 1.5 mm in C, D.
